How can you tell the gender of a goldfish?

My child got a goldfish and want to know if it's a boy or girl.

Sexing a goldfish is almost impossible until the fish has reached breeding age, usually about one year old. Males develop white pimple like spots on the gills, and females will become longer because they fill with roe, and have a larger vent than males. The vent is found before the anal fin.

Male goldfish have pointed pectoral fins with a stiffer leading ray. The female goldfish has a shorter more finer front fin ray, and pectoral fins are rounded.

the gender of a goldfish is determined at the bottom of it. There will be a number pelvic fins if it is male. females have either no/considerably smaller fins

The only way to sex your goldfish is to look up reference pictures. Without actually seeing the differences, you will not be able to tell; even then it will be difficult. Check google for references.
